Specification of Letters Patent.

Patented May 25, 19in?.

Application led October 4, 1913. Serial No. 793,363.

To all whom t may concern Be it known that I, ALBERT EDWARD UrcKLiN, a subject of the King of Great Britain, residing at Goodmayes, Essex, Fmgland, have invented certain new and useful Improvements in Devices for Making Damp-Sand Bricks and the like, of which the following is a specification.

rIhis invention relates to that class of device principally used by children for making bricks and similar articles from damp sand but can be employed for making bricks of other' material for use commercially and constructed of box form with a division plate between the open top and bot- I tom and provided with means for ejecting the brick which is-made in one of the compartments, and consists of an improved construction of such devices whereby they are made cheaply, are easier to handle, and there is no liability of the brick falling out while the appliance is being handled.

The chief feature of my invention is to pivot one or both of the sides of the box mold so that they can be opened out to release the brick, the brick being retained within the mold while being carried about by providing the sides with projections or by positioning the one or both sides at a slight angle to each other. so as to retain the brick in the mold.

The pivoted sides may be locked together by a bar or other suitable device and be actuated for opening or closing by such bar, or such sides may be free and be held closed or open by the hand.

I will describe and illustrate my invention in the preferred form, that is a construction in which the sides are held and actuated by a bar.

According to the annexed drawings, Figure l is an end view partly in section of the mold box with the sides closed. Fig. 2 is an end view with the sides open. Fig. 3 is a longitudinal section of the mold box with the sides closed. In the above figures the mold is in position for depositing the brick. Fig. A is a plan showing the sides open. Figs. 5, 6, 7, and 8 are detail end elevations of slightly modified forms of mold box with the end wall removed.

According to my invention I construct the mold box when making a brick of the usual shape, from two ends A, A, and two sides B, B, the sides B, B, being pivoted preferably to the ends A, A, at C, C, or the sides may be pivoted or hinged (as shown in Fig. 6,) to the division plate D, which forms the bottom or base of the mold box.

Just below or about level with the pivot pins C, C, of the sides, I position a division plate or bottom D, this being secured to the ends A, A,`and forming the box mold into two open compartments, the larger of which is used for molding the brick. On each inner wall of the sides B, B, I may secure a projecting piece E, E, this serving to retain the molded brick within the box as hereafter explained or instead one or both sides may Abe made to close in slightly together so as to form one compartment of a slight wedge shape (as shown in Fig, 7). VAccording to this construction the mold can be placed upside down and the sides held in position by the hand, the box is then filled with sand and the sand pressed therein, the mold is then carefully lifted with the sides still in position and the mold is turned over and placed in the position it is desired to place the brick, the pivoted sides are then opened out by pressing the upper ends together and the mold lifted leaving the brick n situ. The ends may have stops b to limit the inward movement of the sides as shown in Fig. 8, or may be free and held open or closed by hand as indicated in Fig. 5.

n As this construction requires careful manipulating by hand to keep the sides in proper position I prefer to provide means for normally keeping the pivoted sides closed and as shown on the annexed drawings, Figs. 1, 2 and 3, I position a bar E across the end pieces A, A, and secure same thereto and at the center of this bar E and to the division wall D, I pivot at F a bar G extending acrossy the mold and provided at its ends with hooks H, I-I, formed on a strip Gr secured to the top of the bar G or the hooks may form part of the bar Gr which engage the pivoted sides B, B, and with the bar G hold them in position. 0n opposite sides of an imaginary line across the mold and through the pivot F, I form recesses I, I, in the pivoted sides B, B, as shown.

In action when the bar G is positioned across the box, the ends of the locking bar G engage the inner faces of the pivoted sides B, B, and the hooks H engage the outer faces thereof and hold them in position ready for the larger compartment to be filled with sand or the mold being placed upside down and after the sand has been rammed home and made flush with the edges of the mold theV device can be lifted, turned upside down and carried about without fear of the brick falling out due to its being re# tained within the compartment by the projections E or by the pivoted sides B, B, being at an angle to each other' instead of parallel.

After the mold with the brick has been placed where it is desired to deposit the brick the bar G is turned about its pivot F so as to release the sides B, B, while the hooks I I will act upon the exterior of the sides B, B, and will draw in theJ upper edges of the sides B, B, and consequently openout the lower portions until the projections E are clear of the sides of the brick as at Fig. 2, the recesses I in the sides B, B, permitting this movement when the mold can be lifted leaving the brick n situ. By reversing the movement of the bar G Athe sides B, B, can be closedv in and a fresh brick made.

The mold may be of anyv desired shape and the pivoted sides positioned to suit the shape ofy brick and any device or marking may be made upon the sides or the division plate to ornament or shape the brick.

The device is preferably made in wood but itcan be made of metal or partly of metal and partly of wood.

What I do claim as my invention and desire to secure by Letters Patent is l. A mold box for forming bricks and the like, comprising a bottom, and laterally arranged side and end walls, extending above and below the bottom, one pair of said walls opposite to each other being pivoted between their longitudinal edges, and a locking device secured tosaid bottom, on the outer side thereof and between projecting portions of said pivoted walls, by a pivotal connection having its axis perpendicular to said bottom, and provided with portions for engaging the inner faces of the exterior projecting portions of said pivoted walls beyond their pivotal axes for rocking said walls on said axes into and holding said walls in operative position.

2. A mold box for forming bricks and the like, comprising a bottom, and laterally arranged side and end walls, extending above and below the bottom, one pair of said walls opposite to each other being vpivoted between their longitudinal edges, and a locking ldevice secured to said bottom, on the outer side thereof and between projecting portions of said pivoted walls, by a pivotal connection having its axis perpendicular to said bottom, and provided with portions at each end for engaging the inner and outer faces of the exterior projecting portions of said pivoted walls beyond the pivotal axes for rocking said wallsl on said axes into and holding them in operativeposition and to positively swing them on their pivots to disj charge the molded form.

3. A mold box for forming bricks and the like, comprising a bottom, end walls and side walls having portions extending above and below said bottom, said end walls being ner faces of said pivoted walls and hold them in closed position, said locking bar v being provided at its ends with hookpor'-V tions Yfor engaging the outer faces of said pivoted walls to positively draw them toward each other and separate the opposite portions which engage the molded form,

lsaid side walls being provided with recessed portions to engage the locking bar when in open position. Y

A4. A mold box for forming bricks and the like, comprising a bottom, end walls and side walls having portions extending above and below said bottom, said end walls being rigidly secured to said bottom and said side walls being pivoted horizontally "between their upper and lower edges, a locking bar pivoted on the outer face of the bottom, between the exterior projecting portions of the pivoted side walls, by a vertical pivot and having end portions to engage the inner faces of said pivoted walls and hold them in closed position, said locking bar being provided at its ends with hookportions for engaging the outerA faces of said pivoted walls to positively draw them toward each other and separate the opposite portions which engage the molded form, said side walls being provided with recessed portions to engage the locking bar when in open position, and said pivoted side walls yhaving their inner faces provided withprojecting portions extending into the mold box to form recesses in the molded form, and assist in retaining it in the mold box when the said pivoted walls are in closed position.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ALBERT EDWARD NICKLIN.
